The Western horror story, which premiered last year at the Toronto International Film Festival, centers on Lizzy Macklin (Caitlin Gerard, “Insidious: The Last Key”), a capable German immigrant working to carve out a life alongside her God-fearing husband Isaac (Ashley Zukerman) on a remote stretch of the American frontier. When newcomers Emma and Gideon Harper (Julia Goldani Telles and Dylan McTee) set up homestead nearby, their arrival stirs up Lizzy’s dormant fears of a sinister presence haunting the land and sets off a harrowing chain of events.
